[@creepyloner1979]

bonus tip: if you want a perfectly smooth, round hole with more resistance to delamination, make the hole oversized and print an inner liner vertically that you then glue or friction fit into the oversized hole. this also helps with clearance issues because you can just adjust and reprint the liner to get the exact fit you want with minimal waste.

[@learningtocrash4030]

This can also make the part stronger at this potentially high stress area by orienting the pieces at 90 degrees like plywood. The insert could also act like a ring to keep screws from splitting the main part with layers parallel to the screw

[@gabiold]

This is a clever idea!

[@martinsmith2948]

this is an amazing tip! blew my mind! thanks!!!

[@75new]

Thank you for being the only 3D printing channel who uses the terms "tolerance" and "clearance" properly!

[@EpicHeroSandwich]

love the compliant bearing hole design!

[@lukasdon0007]

It's also worthwhile to remind people about *PLA creep*; even if the fit is very snug and tight, and even if you use screws to clamp it, PLA will deform over time under constant loads. So a hole which was initially very snug and tight, will after a few months be loose because the PLA has permanently deformed. So any design that requires snug fits and constant stresses, should be printed in other types of plastic that don't suffer from this (really annoying) property.

[@jacen3716]

Very impressive design skills! I'm impressed you designed your own printer!

[@ChrisRiley]

Hey Angus, I know this is an old video, but I was searching around on some Fusion tips and teardrop holes are a real game changer when folks start designing. I am always happy when I see videos that are so helpful to others. I always appreciate what you do.

[@zaSpeaker]

Thanks for the tips. I've always had trouble shoving my rod in a hole.

[@cheroso1000]

This is the best 3D print/maker channel by far! Thanks a lot!

[@elmariachi5133]

Pro hint: Don't print the holes - print the matter around the holes! :)

[@tin2001]

There is no spoon.

[@ransombot]

The hole truth.

[@da-n-ny1742]

I usually add about 0.5mm to the radius to allow for material expansion with any hole. Even then some are too small and use a razor, drill or deburring tool. A lot depends on the nozzle size, print orientation and detail settings of the slicing software as well.

[@saeed6811]

Simpler fix: 1. Design a bit larger hole so that when you print, you get more tolerance. 2. Drill a bit smaller hole then rim it with a rimming tool to your proffered size.

[@ihatenumberinemail]

@@saeed6811 *reaming tool

[@FilamentFriday]

7:02 - You need a deburring tool to clean out those holes. Nice tips.

[@jeric_synergy8581]

Thirded. C'mon, they are one of the cheapest tools out there.

[@3dbatman126]

My experience, it's hard to keep deburring tool centered. I resorted to vertical stand drill. But looks aside I now would employ Angus' teardrop holes for simplicity.

[@TheMidnightSmith]

Dude I'm so stoked to see this! Thank you!

[@RonFloyd]

Some really cool tips Angus! In addition to the last example, at 6:32, if you needed to, you could always drive 3D printed wedges (or even just wood screws) into the "smiley face" cutouts to make the fit even tighter.

[@h0ll1s]

This is great Angus, awesome to see your designs!!

[@Leadingedgeindustrial]

Fantastic video, as always, Angus! Thanks for sharing these tricks with us!

Amazing !!! Your videos are going to become insane if you keep going down this path ! Keep it up man solid content as always.

[@SamsDesigns]

Way to go again Angus! Great tips!

[@cncmillworks2779]

Thank You, I just designed 18mm x 50mm cable chain links for my CNC and the tear drop trick will really help. I was having to file the tops back into round. You most definitely help to empower.

Great tips Angus, love the teardrop! Keep up the great work!

[@theimpatientbrewer]

Excellent video, always waiting with baited breath for the next one.

[@BenRyherd]

Good design tips even for the more seasoned designer. On the teardrop holes, with everything ideal your slicer and printer should work together to where the "Flat spot" at the top of the hole is at the correct height. It's possible that you get a small amount of droop when printing that bridge that makes those holes too small. For the sake of proper parametric sketches, it'd be far better to define the angle of that point, then you could make it 40 to 50 degrees to the horizontal to ensure that the overhang can be printed and that also allows you to change the diameter of that hole without having to also change the dimension you had to the point. For example you had an 8.2mm hole for your rod and 5mm from the center of the circle to the point of the teardrop. If you decided later to go to 6mm rods your teardrop would have a much sharper point and a much larger amount of material removed relative to the size of the rod. If you decided to go up to 12mm rods your "Point" of the teardrop would be inside your circle. This in conjunction with your tangent mates would probably throw up an error on that sketch until you changed the dimension for that point. I'm sure you were building based off of a preset pile of parts and you knew what size was going in there and weren't going to change your mind but practicing Parametric modeling even where it's not necessary really helps keep up skills (In my opinion anyways).

Well-stated, Ben! Thank you for your invaluable insight.

[@gabiold]

All this can be eliminated if you simply constrain the angle of the spike, not the height. It will not completely be aesthetically pleasing as it will look too high for bigger holes. You can avoid that if you specify the height, but not from the center rather from the perimenter and you have to drop the tangential constraint. The phenomenon is that with smaller holes the layer hight thus the quantization effect has much bigger impact on the accuracy that with bigger holes. You can print a larger hole with proportionally smaller teardrop.

[@AdultsSwim1]

Great tips! I especially loved the teardrop idea. Your bridging technique instead of supports also looks interesting. Can't wait to see it in action!

[@oldsalty3d122]

Nice! Your timing was perfect! I needed those tips for a print design I'm currently working on at the moment. Going to implement your tips right now. Thanks so much Angus, your awesome!!

[@lionelmartinez7044]

Angus, awesome tips. i have already used your tips on some fixture designs and wow what a difference. usually we end up reaming the holes to get a tight fit but using these techniques really our post process down. i've shared your video to my coworks to help them design for 3D print as well. Thanks Angus

[@xavimourelo]

Wow, these tips are awesome! I could be watching this kind of videos for hours, very useful. Please do more tips!

[@KiR_3d]

Wow! These tips about holes are really great! The 3rd is just a master piece! It can be thought out but you've made this for us! :)

Angus, I am very new to CAD design and 3D printing. However, the information contained herein is EXCELLENT. Very good tips; much appreciated. This will save time and trouble down the road as I try to master this new knowledge base. Thank you for sharing.

[@pedrohenriqueboscofi]

Big thanks for sharing those tips, I've been following the channel for a long time now and always had in mind a project that shares a lot of similarities to that one. It is good to see the things that I thought that were in line with how you did and it worked, and even cooler to discover both that drop shape hole and the hole fingers techniques! thank you!

Bloody brilliant, New to printing with my Ender3, I have learned so much from your vids, Esspecially about getting 360 for free!

[@MFEeee]

Thank you. The slot for fitting bearings is genius! Printed a CNC router bracket to accommodate a bldc motor. My bearing holes came out too small and I don’t have a drill bit big enough to expand the hole. Tried friction pressing a 10mm socket with a wrench. Expanded a bit but cracked the piece. Printed in ABS. Going to try this. Thanks again!
